WEST NEW YORK, NJ - The FBI on Friday removed a computer from the New Jersey home of a sister of the Boston Marathon bombing suspects. Police said she was cooperating with the investigation and was "heartbroken, surprised and upset," though she told reporters she wasn't sure the accusations against her brothers were true.

The woman, identified by local police as Ailina Tsarnaeva, told federal agents she had not been in contact with her brothers for years, according to Police Director Michael Indri.

Her brother Tamerlan Tsarnaev, 26, was killed overnight in a shootout with police outside Boston. Her younger brother remains at large.

"He was a great person," the woman said of her dead brother. "I thought I knew him. I never would have expected that from him. He is a kind and loving man. The cops took his life away just the same way he took others' lives away, if that's even true. At the end of the day, no one knows the truth."

The sister last spoke to Colon on April 6, Colon's birthday. Colon said she saw a Facebook posting Thursday night that led her to believe the woman may not have known her brothers had been identified as suspects.
